Perhaps you should try some spelling variations:
"legal environment performance targets." » "legal environmental performances targets.", "legal government performance targets.", "legal investment performance targets.", "global environment performance targets."
"level environmental performance metrics." » "local environmental performance metrics.", "global environmental performance metrics.", "better environmental performance metrics.", "level environmental performance contracts.", "level environmental performance measures.", "level environmental performance contract."

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("level environmental performance metrics.") OR ("legal environment performance targets."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"level environmental performance metrics.\") OR (\"legal environment performance targets.\"))*".
• Removing quotes may allow a broader search: (( level environmental performance metrics. ) OR ( legal environment performance targets. ))*.
